Power source part Power source Used circuit Vcc(DC 5V) Surrounding power of MICOM and sensor detection part +2V(DC 12V) Relay driving part, panel display part BLDC(DC 12V) OP AMP, TR constant voltage circuit use(BLDC fan motor drive) AC 220V input power is reduced by passing through LVT(DC-TRANS), this power is changed to DC voltage through rectification diode. After this, DC 12V leveled by 1000uF/35V capacitor and settled by regulator 7812 is output and in use for relay and panel PCB driving power, input power and refrigerator control. Another the second of LVT(DC-trans) is leveled by rectification diode and 1000uF/35V capacitor, and controlled to set voltage by OP amp, constant voltage TR circuit, and then supplies a settled voltage to BLDC motor. 10-2. Oscillation circuit part Terminal Oscillation frequency Xin(#30) 4MHz Xout(#31) 4MHz Oscillation circuit is for clock occurrence for synchronism to the information transmission/reception of MICOM internal elements and for time calculation. If the resonator spec is changed, normal function is not performed because of the changing of MICOM timing system. 10-3. Reset circuit part 27 Terminal Voltage Vcc DC 5V RESET DC 5V Reset circuit is that initializes many internal parts of the MICOM and makes the all programs to act in the initial state in case that power is impressed to MICOM by instantaneous interruption or power input. Reset terminal voltage becomes to scores of us “ LOW” compared to the MICOM Vcc((DC 5V) voltage on power impression, and keeps “ HIGH” (Vcc voltage) on the normal action. 10-4. Door S/W detection circuit Terminal Door state MICOM input CLOSE 0V (LOW) OPEN 5V (HIGH) CLOSE 0V (LOW) OPEN 5V (HIGH) F room R room CN30℃ is connected to GND and ② is supplied Vcc(DC 5V) by passing through Resistance R401 (10℃), and it detects F room door open/close by impressing to MICOM “ HIGH(5V)/LOW” . CN30 ℃ is connected to GND and ① is supplied Vcc(DC 5V) by passing through resistance R403(10℃), and it detects R room door open/close by impressing to MICOM “ HIGH(5V)/LOW” If there are some faults in door S/W at this time, the corresponding fan is not act or alarm occurs. Check the door S/W whether it has an abnormality. If the door is opened, the internal corresponding fan stops. This is occurred because MICOM stops the fan deciding door open although door is closed when being S/W contact point abnormality. 10-5. Temperature detection circuit MICOM terminal Voltage Outdoor temperature PIN #57 (F-DEF-SENSOR) MICOM terminal voltage is PIN #58 (R-SENSOR) changed by the PIN #59 (ATMOSPHERE SENSOR) temperature. PIN #56 (F-SENSOR) Sensor makes use of the character that resistance value becomes smaller when temperature is high, and bigger temperature is low by use of thermistor having a indeterminate resistance temperature coefficient. R302,4,6,8 and C301,2,3,5 have no concern with temperature detection because they are for noise protection parts. In case of F-sensor, if the voltage that input to MICOM is supposed to Vf, Vf= (Rth x Vcc)/(R301 + Rth).At this, Rth is a thermistor resistance value. Refer to attached appendix for MICOM terminal voltage corresponded to temperature and resistance/voltage conversion table of sensor. 28 10-6. Key scan and display circuit part 1) Description of key scan and display drive action As a following each part wave, “ HIGH” output is send out, by use of three terminals of MICOM No #5,6,7 by 6 msec intervals. This signal passes through input terminal of IC05 and is displayed to output terminal. At this time, the peak to peak voltage of rectangle wave is about 12V, the shape of output wave is like following. 2) KEY SCAN When GRID #3 wave is output, this signal is supplied to SW1 by passing through panel PCB R5 resistance 10℃. At this time, pressing SW1 makes a signal small by R508(6.8㏀) and R505(12㏀), and impress peak to peak 4.5V to MICOM. MICOM decides that GRID #3 wave is input and changes the function corresponding to SW1. Like this, each GRID wave is recognized. 29 10-7. BLDC MOTOR drive circuit ● Movement description When F-fan is driven to LOW RPM, Resetting the MICOM #40 pin with being set #39 always links the R705 and R707 in a parallel. At this time, the voltage is devided between a parallel resistance value and R706, impressed to OP-AMP. It makes Q1 turn ON, F-fan drive. If F-fan is in condition of OFF, MICOM #39 pin is reset and F-fan is stopped. In case of the Comp.-fan, it is controlled by the same method with F-fan. But its drive voltage is different with that because there is a difference in E1 voltage /E2 voltage due to the difference of RPM. ※ Fan motor protection When the fan is not run because of F-fan/C-fan freezing or power cord connection part inferiority, fan self-signal is not occurred. So MICOM decides fan abnormality. At this time, perform the fan three seconds ON, seven seconds OFF in five times. If there is no signal during the fan ON/OFF five times, after 10 minutes pausing repeat the three seconds ON, seven seconds OFF in five times. If the signal is occurred during the three seconds ON, seven seconds OFF, MICOM decides that operation is normal and releases all motor protect functions and performs a normal function. 30 10-8. Load drive part circuit ● Movement description When “ HIGH” signal is impressed to input terminal of IC04 at MICOM PIN NO #15, IC turns ON. At this time, V12(DC 12V) connected to one side end of Comp relay passes through output of IC04 to ground, and the core of relay causes a magnetic field and makes a contact point on. And AC input voltage(AC 220V) is impressed to the both side end of Comp. load, Comp. acts. In case of the MICOM PIN #15 signal is “ LOW” , IC04 turns off and the current is not flow to Comp. relay coil and makes a relay contact off. And Comp. stops. The load except the compressor equals or likes to the act principal of compressor. Refer to the above circuit diagram. 31 10-9. Damper motor drive part ● Movement description Damper is a 2 excitation type stepping motor used in controlling the refrigerator temperature. It is opened when the temperature is higher than the setting temperature of refrigerator sensor, and closed lower according to the refrigerator notch. It performs a open/close without regardless of refrigerator temperature at power ON, and then decides the state of open/close according to the temperature. Open/close action is controlled by MICOM #34, #35, #37 through damper motor(stepping-motor) exclusive control drive IC(IC8:TA7774P). Damper heater is supplied DC12V whenever voltage impresses to the refrigerator and the signal is occurred always in MICOM #24, DC 12V flows into the damper heater by IC3. ※ Note In case of the above damper heater, because the PCB cannot detect the open/close state, there is no self diagnosis function for deciding the abnormality. IN the above diagram, if a wire cut off linked 3,4,5 of CN7, motor is run as a normal, but refrigerator over cooling occurs by slightly open at the close of damper. So, check for deciding of abnormality of damper motor connection part like followings. 1) Check method : After separation of CN72 housing, measure the resistance value by use of multi tester and decide the abnormality. 2) Resistance value spec ①-② (black, brown) : 150Ω±15% ③-④ (white, blue) : 426Ω±15% ⑤-⑥ (yellow, red) : 426Ω±15% 32 10-10.
